How to monitor Cassandra performance metrics. : Approximate number of pending task. : Estimated number of tasks pending. There are enough that listing them here would be counterproductive; however they fall into the following groups: Index - Metrics specific to a single index. Below are modern JMX paths, which mirror the JConsole interface’s folder structure, for the key metrics described in this article: * The metrics needed to monitor recent latency and key cache hit rate are available in JConsole, but must be calculated from two separate metrics. If ColumnFamily is for secondary index, then type will be IndexColumnFamily. MemtableDataSize JMX and MBeans. ActiveTasks : Approximate number of tasks thread pool is actively executing. Prior to Cassandra 2.2, many identical or similar metrics were also available via alternate JMX paths (org.apache.cassandra.db, org.apache.cassandra.internal, etc. PendingTasks To enable a reporter: Add the relevant reporter library (such as metrics-ganglia) to lib. These metrics can be queried via JMX or pushed to external monitoring systems using a number of built in and third party reporter plugins.. Metrics are collected for a single node. cdsh. Create your config file (for example you may want to include or exclude certain per column family metrics). : Total number of unavailable requests. : Currently active outbound streams. To answer these kinds of questions, you need a more sophisticated monitoring system. Start cassandra with -Dcassandra.metricsReporterConfigFile=yourCoolFile.yaml MeanRowSize : Incoming bytes received from specific node. Both the clusters export metrics, but on one of the cluster lesser metrics are being exposed.

ColumnFamily metrics are created per ColumnFamily. cassandra-ca-manager. By default, Apache Cassandra restricts JMX communications to localhost only. $ docker run -d --rm --name jmx -p 5000:5000 sysdiglabs/jmx-metrics:0.1 Check out your jmx monitoring metrics by running jconsole and connecting to the local process: You will receive a security warning (no-SSL endpoint), it is safe to continue in this case. CommandPendingTasks By default nodetool prints statistics on all keyspaces and column families, but you can limit the query to a single keyspace by appending the name of the keyspace to the command: nodetool compactionstats shows the compactions in progess as well as a count of pending compaction tasks. In the JConsole GUI, click the MBeans tab. Configure Cassandra Monitoring Extension. The Cassandra Nodetool check is included in the Datadog Agent package, so you don’t need to install anything else on your Cassandra nodes. : Estimated number of completed compaction tasks. cassandra-exporter is fast. (See the first footnote on the table below for exceptions.) You can specify which node you’d like to inspect by using the --host argument with an IP address or hostname: nodetool cfstats provides statistics on each keyspace and column family (akin to databases and database tables, respectively), including read latency, write latency, and total disk space used. : Total latecy in micro seconds.
